I thought of these around Girls Day, when I wanted to make something pretty and with a spring theme.

For Step 1: If the carrot slice is too thick, it's difficult to work with. So, if you want to make a lot of flower petals, it's better to make multiple petals instead of thinly slicing one large petal.
For Step 4: The shape will hold better if you keep the petals firm and don't overcook them.
I overcooked mine in the microwave and they turned out mushy... Recipe by Kumanokanaho
